footprint must be separated from the closest edge of an adjacent mapped medium, high or
very-high potential bushfire intensity area by a distance (APZ width) that achieves a radiant
heat flux level of 10 kW/m? or less at all development footprint boundaries.

The proposed development footprint achieves <10kW/m? RHF exposure from the High and
Medium Potential Intensity Areas associated with the VHC 8.1, VHC 9.1, and VHC 36.1
vegetation hence satisfies the vulnerable use setback criteria. Therefore, no specific APZ’s
are required about the proposed infrastructure location whilst site conditions remain as they
are detailed herein.

It is recommended future landscaping does not exacerbate the bushfire hazard risk on the site
and result in separation between infrastrcuture and hazardous vegetation that generates non-
compliance with the vulnerable use setback criteria.

5.3 Water Supply

The availability of a reliable water supply for firefighting purposes is a vital tool in the defence
of bushfire impact. Reticulated water supply is currently not available within the site nor
proposed to be connected to the site. Therefore, any proposed buildings in the confirmed
bushfire prone areas (refer Plan BFO3) within the site require provision of a readily accessible
on-site emergency static water supply in accordance with Assessment Benchmark 4 of the
SPP Bushfire 2019. Assessment Benchmark 4 references the QFES 2019 Bushfire Resilient
Communities document for information regarding appropriate static water supply. Section 9.1
of Bushfire Resilient Communities’ states:

An appropriate static water supply (in bushfire prone areas where reticulated supply is not
provided) to support effective emergency services response includes a water tank that is
available solely for firefighting purposes and can be accessed by firefighting appliances. The
water tank is to be provided within 10 metres of each building (other than a class 10 building),
which:

a) is either below ground level or of non-flammable construction;

b) has a take-off connection at a level that allows the following dedicated, static water supply
to be left available for access by firefighters:

i.10,000 litres for residential buildings;

Only the eastern wing of cabins (7 cabins total) is captured within a confirmed bushfire prone
area (refer Plate 20). The approximately footprint of all 7 cabins captured within the confirmed
bushfire prone area is 320m which is about the size of a single large residential building.
Therefore, the provision of 10,000 litres to service all 7 cabins is sufficient.

It is noted that a 300,000 litres tank is proposed adjacent to the southeast eastern wing of
cabins. The required 10,000 litres can be provided within this larger tank or alternatively as a
separate 10,000 litres tank which should be located centrally to all cabins.

The 10,000 litres supply is to be reserved for firefighting purposes only to be shared between
2 cabins. Plate 21 outlines an example of reserve water supply in a standard tank.
